CVE-2023-49411Public exploitNetwork attack vector

Router crash via oversized deleteMesh MAC value

Published Dec 7, 2023 · Updated Aug 2, 2024

Stack overflow in formDeleteMeshNode in Tenda W30E 16.01.0.12(4843) allows remote attackers to crash the router via an HTTP request. The deleteMesh handler processes an oversized mac value in JSON posted to /goform/module, overflowing the stack in formDeleteMeshNode. NVD assesses exploitation as unauthenticated with no user interaction; the published proof demonstrates denial of service, not code execution.
